| 20100274069 | METHOD FOR BIOREMEDIATION OF HIGHLY AROMATIC HYDROCARBON WASTES - Disclosed herein is a method for biopile-based bioremediation of hydrocarbon waste with high aromatic content. The method comprises of isolating specific microorganisms and preparing microbial blend, preparing biopile, adding the microbial blend into the biopile, providing nutrient, aeration and watering of biopile. | 10-28-2010 |
| 20100243533 | EXTRACTION OF AROMATICS FROM HYDROCARBON OIL USING N-METHYL 2-PYRROLIDONE AND CO-SOLVENT - The present invention provides a process for extraction of aromatic material from hydrocarbon oil by using a solvent mixture comprising N-Methyl-2-Pyrrolidone (NMP), at least one co-solvent and optionally water, to obtain a raffinate. The process of the present invention lowers operating cost as the cost of the co-solvent employed is lower than that of neat NMP. Another feature of the present invention is that it produces the same quality raffinate as those of neat NMP-water measured by the refractive index but produces higher yield of raffinate at same feed to solvent mixture ratio. | 09-30-2010 |
| 20100176025 | PROCESS FOR UPGRADING OF LIQUID HYDROCARBON FUELS - Disclosed herein a process for upgrading the liquid hydrocarbon fuels by reducing aromatic content, sulfur content and nitrogen content wherein the process comprising isolating polycyclic aromatic hydrocarbon (PAH) transforming microbes and preparing biocatalyst by mutagenesis, contacting the biocatalyst with the liquid hydrocarbon fuel in an aqueous medium for transforming the aromatic, sulfur, and nitrogen containing compounds to polar substances, subjecting the mixture of biocatalyst and the liquid hydrocarbon fuel to a process of bioconversion, removing the polar substances by liquid-liquid extraction with a polar solvent to obtain dearomatized, desulphurised and denitrogenated liquid hydrocarbon fuel and recovering the upgraded liquid hydrocarbon fuel. | 07-15-2010 |
| 20090325271 | METHOD FOR BIO-ASSISTED TREATMENT OF HYDROCARBON CONTAMINATED SOIL - Disclosed herein is a bio-assisted method for treatment of hydrocarbon contaminated soil employing novel microbes which are capable of decontaminating hydrocarbon contaminated soil having free flowing water or in slurry form or having large amount of gravels. The method comprises adding hydrocarbon releasing microbes followed by adding the microbes capable of degrading the released hydrocarbon to decontaminate the soil, wherein said microbes are grown separately in suitable vessels containing a suitable nutrient medium. | 12-31-2009 |
| 20090217571 | METHOD FOR BIO-OXIDATIVE DESULFURIZATION OF LIQUID HYDROCARBON FUELS AND PRODUCT THEREOF - Disclosed herein is a method for producing ultra-low-sulfur content hydrocarbon fuel and product thereof. The method comprises selective biocatalytic oxidation of sulfur containing compounds present in the fuels employing enzyme lipase as biocatalyst in presence of controlled and incremental amount of hydrogen peroxide and carboxylic acid without using water or any co-factor for the reactivity of said enzymes. | 09-03-2009 |
| 20090038211 | NOVEL SYNTHETIC FUEL AND METHOD OF PREPARATION THEREOF - Disclosed is a novel synthetic fuel as alternative to diesel, wherein said synthetic fuel comprises branched esters and wherein the fuel having improved fuel properties such as zero aromatic, zero olefin, zero sulphur, low pour, high cetane diesel fuel with improved lubricity and oxidative stability. Further, the present invention provides a method of preparation of said esters. | 02-12-2009 |
